To provide a protective plate-coupling method which improves the quality of a joint part of protective plates, keeps consistency between a protective material layer and a coupling sheet in the joint part, and improves operational efficiency.
Protective plates A and A, which are adjacent to each other, are arranged to form a gap, and the adjacent protective plates are coupled with each other with a lower side coupling sheet to form a cavity 4 to be filled. The upper surface aperture part of the cavity 4 to be filled is covered with an upper side coupling sheet B1 which is formed of a transparent or translucent material, and both the side end parts of the upper side coupling sheet B1 are placed on the adjacent protective plates, and the one side end part of the upper side coupling sheet B1 is coupled with one protective plate A, and the other side end part of the upper side coupling sheet B1 is coupled with the other protective plate A in the direction of the length of the cavity 4 to be filled. Then, the injection hole of an injecting machine is inserted into the cavity 4 to be filled, from the unjointed part between the other side end part of the upper side coupling sheet B1 and the other protective plate, to inject a setting-type protective material into the cavity 4 to be filled at the jointed part.
